FIG. 1 illustrates an embodiment of a vehicle 10 that facilitates thedeployment of a mobile surveillance module 18. Vehicle 10 includes afirst portion 12, a second portion 14, a third portion 16, a module 18,a lifting mechanism 20, and jacks 24. Vehicle 10 equipped with module 18enhances a user's ability to survey an area.

Vehicle 10 represents any suitable transportation apparatus that housesmodule 18. In the illustrated embodiment, vehicle 10 is a van. In otherembodiments, vehicle 10 may be a recreational vehicle, a tank, a sportsutility vehicle, a bus, a pick-up cab chassis with an added box, acutaway vehicle with a walk-in step or a multi-step body, a bobtailtruck, a box van, a hybrid van, any tactical coach, any tactical commandpost, a delivery van, any wheeled vehicle, any tracked vehicle, or anyother transportation apparatus that is capable of accommodating module18. A user may use vehicle 10 for surveillance, security, military, lawenforcement, and/or traffic control applications.

Vehicle 10 includes any suitable component that allows a user to operatevehicle 10. For example, in the illustrated embodiment, vehicle 10includes four tires that allow a user to drive vehicle 10 on a surface28. Vehicle 10 may also include four-wheel drive to improve thedrivability of vehicle 10 in different weather conditions or ondifferent surfaces. In the illustrated embodiment, vehicle 10 includes afirst portion 12, a second portion 14, a third portion 16, and a base 22that include components to facilitate the operation of vehicle 10 andmodule 18. The components in first portion 12, second portion 14, andthird portion 16 are only illustrative and each of first portion 12,second portion 14, and third portion 15 may include one or morecomponents that are distributed or consolidated within one or more ofthe portions. First portion 12, second portion 14, and third portion 16represent different areas of vehicle 10 and may be combined as a singleunit.

First portion 12 includes components that allow a user to operatevehicle 10. For example, first portion 12 includes a steering wheel,seats for a driver and a passenger, an interface to control module 18,an engine, a transmission, a front suspension, shock absorbers, anemergency parking brake, other internal automotive components, steps fora user to enter module 18, and any other component that allows a user tooperate vehicle 10. First portion 12 may also include components toenhance a user's experience while in vehicle 10, such as a radio, airconditioning, a heater, power windows, and/or power door locks.

Second portion 14 also includes components to facilitate the operationof vehicle 10. For example, second portion 14 includes a rearsuspension, shock absorbers, module 18, and a lifting mechanism 20.Second portion 14 also includes control components, such as a processor,a hydraulic unit, a memory, sensors, and actuators as described below inFIG. 3. In an embodiment, the rear suspension accommodates the increasedload capacity presented by module 18 and lifting mechanism 20.

Third portion 16 represents an extension of vehicle 10 that accommodatesmodule 18. Third portion 16 may include a fabricated bonnet made of anysuitable material, such as fiberglass, aluminum, or reinforced plastic.In an embodiment, vehicle 10 may be retrofitted to include third portion16. In another embodiment, vehicle 10 includes third portion 16, andappears as a single element from the exterior before module 18 extends.When module 18 is retracted, it is not detectable from outside vehicle10. In the illustrated embodiment, third portion 16 has an opening 36that module 18 and lifting mechanism 20 extend through duringdeployment.

Module 18 represents an enclosed, self-contained capsule within vehicle10 that a user may enter from first portion 12 and occupy to survey asurrounding area when module 18 deploys. Module 18 may be a fiberglasscapsule, an aluminum capsule, a steel capsule, or a reinforced plasticcapsule. Module 18 may accommodate any number of users up to a maximumweight capacity. In an embodiment, a driver of vehicle 10 moves intomodule 18 and occupies module 18. In the illustrated embodiment, thewalls 19 of module 18 taper from top to bottom to maximize the interiorspace. Tapered walls 19 also improve the movement of module 18 duringdeployment and retraction. More specifically, tapered walls 19 serve toself-center and align module 18 with the installation of replaceable rubpads 41 on each side of module 18. Pads 41 guide module 18 into opening36 to provide a sealed area. Tapered walls 19 also secure module 18 in astowed position while vehicle 10 is in motion. A user may customizemodule 18 to meet specific requirements. In one embodiment, module 18includes an anti-shear bracket and lock to prevent movement of module 18while vehicle 10 is moving. FIG. 2 describes a particular embodiment ofmodule 18 and the components within module 18 in greater detail.

Lifting mechanism 20 represents any suitable mechanism to extend andretract module 18. For example, lifting mechanism 20 may be anarticulating boom, a telescopic cylinder, or a scissor lift. In aparticular embodiment, lifting mechanism 20 is a hydraulic scissor lift.In a particular embodiment, lifting mechanism 20 has scissor arms thatare 3″×5″ hollow, rectangular steel sections that include: steel pivotpins having zinc electroplating to prevent corrosion andself-lubricating pivot bearings that do not require external lubricationor maintenance. Lifting mechanism 20 also may include sensors to ensurethe unit is level before extending. In a particular embodiment, liftingmechanism 20 levels to at least two degrees from side-to-side and to atleast two degrees from front-to-back. Lifting mechanism 20 extendsvertically to any suitable height. In an embodiment, lifting mechanism20 extends nineteen-feet above base 22 of vehicle 10. In the illustratedembodiment, lifting mechanism 20 has a rated net load of 1,350 poundsand a gross certified lift capacity of 2,000 pounds. Lifting mechanism20 mounts to vehicle 10 using any rigid, structural mount, such as astack-to-chassis mount or a designed steel slide mount. Liftingmechanism 20 may attach to the frame of vehicle 10 with bolts and mayattach to the bottom of module 18 using the mount. The mount providesthe necessary support for lifting mechanism 18 without puttingadditional stresses into the chassis frame. In fact, the mount increasesthe strength of the chassis frame. The mount also aligns liftingmechanism 20 and prevents movement of lifting mechanism 20 while in theretracted position and while vehicle 10 is moving. In anotherembodiment, lifting mechanism 20 also includes an anti-shear bracket andlock to prevent movement of lifting mechanism 20 while in the compressedposition and while vehicle 10 is moving.

Base 22 represents the bottom of vehicle 10 and has a first side and asecond side. The first side is inside the vehicle and the second side isoutside the vehicle. Base 22 may include the undercarriage, a frame, orother structural component of vehicle 10. In the illustrated embodiment,lifting mechanism 18 attaches to the first side of base 22 and jacks 24mount to the second side of base 22 and extend from the second side.

Vehicle 10 may include any suitable number of jacks to adequatelystabilize vehicle 10. For example, vehicle 10 includes two jacks 24 thatmount between the front and rear tires of vehicle 10. As anotherexample, vehicle 10 includes three jacks 24. One jack 24 mounts betweenthe front tires and the other two jacks 24 mount near the rear tires insecond portion 14. In the illustrated embodiment, vehicle 10 includesfour jacks 24. Two jacks 24 are located in first portion 12 and twojacks 24 are located in second portion 14. In an embodiment, each jack24 is located near a tire. This provides additional support for thevehicle when module 18 deploys. In a particular embodiment, jacks 24 infirst portion 12 are in front of the tires and jacks 24 in secondportion 14 are behind the tires. Increasing the distance between jacks24 improves the stability of vehicle 10, and the location of jacks 24provides for an isometric advantage for vehicle 10. Jacks 24 may alsomount behind the front and rear bumpers and the side portions of vehicle10. This allows for the concealment of jacks 24 while in the retractedposition and protects jacks 24 from external conditions.

Jacks 24 mount to a frame positioned on the second side of base 22 andextend from base 22 to stabilize vehicle 10 on surface 28. Jacks 24 maybe mechanical jacks, hydraulic jacks, strand jacks, spring-loaded jacks,electro-mechanical linear jacks, or any other devices operable to lift aheavy load. Jacks 24 are capable of handling any amount of force. Forexample, each jack 24 generates 7,850 pounds of force. Each jack 24includes a pad that contacts surface 28 to distribute the weight ofvehicle 10 over an area. In a particular embodiment, jacks 24 are partof a electro-hydraulic stabilization system. Jacks 24 may be metal orsteel and integrate within vehicle 10 by mounting to the second side ofbase 22. The actuation of jacks 24 is described in greater detail withrespect to FIG. 3.

In an embodiment, jacks 24 operate in multiple modes. In a first mode,jacks 24 extend from base 22 to contact surface 28. In a second mode,jacks 24 adjust cooperatively to level vehicle 10. Jacks 24 may adjustaccording to signals from a pressure sensing transducer, a proximityswitch, or a floating jack with a proximity switch. In this mode, jacks24 have a maximum adjustment capability, or stroke, and may not levelvehicle 10 within safe tolerances depending on the condition andvariances in surface 28. In association with the stabilization system,jacks 24 level vehicle 10 to within 5″ from front-to-back and to within2.5″ from side-to-side. If jacks 24 cannot adjust to level vehicle 10, auser may move vehicle 10 to a new position. In a third mode, jacks 24remain fixed. While the stabilization system may continue to sensewhether vehicle 10 is level in this mode, jacks 24 may not adjust theirposition without user intervention or further action from thestabilization system.

Vehicle 10 may operate on any suitable surface, such as sand, dirt,pavement, concrete, and/or grass. Surface 28 may be soft, hard, angled,wet, or dry. Jacks 24 may adapt to a variety of conditions and variancesof surface 28. For example, jack 24 senses that surface 28 is soft andstabilizes after adjusting and sensing surface 28. As another example,one jack 24 may sense a soft surface 28 while another jack 24 senses ahard surface 28. Each jack 24 adjusts according to different surfaces28. As yet another example, jack 24 senses an uneven, soft, andunpredictable surface 28. If jacks 24 cannot level vehicle 10 on surface28, module 18 may not extend. As another example, surface 28 is solid,but there is a height difference between jacks 24 as jacks 24 contactsurface 28. If the height difference is too great to overcome the givenmaximum stroke of jacks 24, module 18 may not extend.

FIG. 1A illustrates a detailed perspective of the uppermost portions ofvehicle 10 and module 18. Top 30 represents the uppermost part of thirdportion 16. Top 30 may be any material that withstands external elementsand conditions. For example, top 30 is aluminum, reinforced plastic,metal, steel, or fiberglass. Top 30 protects the components withinsecond portion 14 and third portion 16 from external conditions. Roof 32couples to top 30 of third portion 16 when module 18 is in the retractedposition. In the illustrated embodiment, top 30 defines an opening 36 toaccommodate module 18. A rim 37 around opening 36 couples to theinterior components of roof 32 to create a tight, waterproof seal.

Roof 32 of module 18 may be formed of aluminum, reinforced plastic,metal, steel, or fiberglass and protects a user within module 18 fromexternal conditions. In the illustrated embodiment, the interiorcomponents of roof 32 include a lip 38, a first weather strip 39, and asecond weather strip 40. Rim 37 of top 30 couples to lip 38 of roof 32to create the seal. Any suitable pliable material may be used to ensurea tight seal between top 30 and roof 32. For example, weather strip 39may include a rubber seal or extrusion, such as Trim-Lok™, and weatherstrip 40 may include a foam weather strip. Rub pad 41 also couples toroof 32 and is positioned on each side of module 18. Rub pad 41 guidesmodule 18 into opening 36 and serves to self-center and align module 18within opening 36. Roof 32 also couples to cover 34. In the illustratedembodiment, roof 32 has an opening 42 to accommodate a camera. A rim 43around opening 42 couples to the interior components of cover 34 tocreate a tight, waterproof seal.

Cover 34 may be formed of aluminum, reinforced plastic, metal, steel, orfiberglass and covers a camera that extends from opening 42. Cover 34also extends when the camera raises. In the illustrated embodiment, theinterior components of cover 34 include a lip 44, a first weather strip45, and a second weather strip 46. Rim 43 of roof 32 couples to lip 44of cover 34 to create the seal. Any suitable pliable material may beused to ensure a tight seal between roof 32 and cover 34. For example,weather strip 45 may include a trim lock weather strip, and weatherstrip 46 may include a foam weather strip. Rub pads 47 also couple tocover 34 and are positioned on each side of cover 34. Rub pads 47 coupleto platform 48, which may hold the camera. Rub pads 47 guide platform 48into opening 42 and serves to self-center and align platform 48 withinopening 42.

In operation, a user positions vehicle 10 in a location to deploy module18. After placing vehicle 10 in park, the user enters module 18 fromfirst portion 12 without exiting vehicle 10. Since the user can accessmodule 18 directly from the driver's seat of vehicle 10 without openingany external doors or windows, this improves safety and convenienceduring surveillance operations. This is a significant improvement overprior systems that required a user to exit a vehicle to enter andoperate a surveillance module.

The deployment sequence begins when a user pushes a button or whenvehicle 10 remains in park for a predetermined period of time. At theinitiation of the deployment sequence, vehicle 10 checks safetyconditions. Safety conditions may include any suitable condition, suchas vehicle 10 being in park, vehicle 10 being stationary for apredetermined period of time, the ignition of vehicle 10 being off, theemergency parking brake being engaged, an entrance to module 18 beingclosed and/or a user being in module 18. Upon a complete check andconfirmation of the initial safety conditions, jacks 24 operate in afirst mode and extend from base 22. Jacks 24 sense the condition ofsurface 28 and, in a second mode, adjust their positioning to levelvehicle 10 responsive to the condition of surface 28. Upon determiningthat vehicle 10 is level, jacks 24 enter the third mode and remainfixed.

Upon reconfirming the initial safety conditions, additional safetyconditions may be confirmed before module 18 extends, such as confirmingthat vehicle 10 is level, confirming that jacks 24 are extended andstable, and/or confirming that an obstruction is not above vehicle 10before module 18 extends. Lifting mechanism 20 then actuates and beginsextending upon the safety conditions being met. As lifting mechanism 20extends, roof 32 of module 18 decouples from rim 37 of top 30, andmodule 18 moves from a retracted position out of third portion 16.Lifting mechanism 20 continues to extend until module 18 is completelyoutside of vehicle 10. In an embodiment, module 18 completely raises inless than thirty seconds to an extended position, and a user insidemodule 18 may have an observation height of over twenty-five feet fromsurface 28.

Upon the completion of the surveillance activities, the user initiates aretraction sequence to compress lifting mechanism 20 and lower module 18from the extended position into third portion 16. Once lifting mechanism20 completely retracts and module 18 is in the retracted position insidethird portion 16, jacks 24 retract into base 22 by user initiation. Whenjacks 24 have retracted into base 22, a user reenters first portion 12from module 18 and moves vehicle 10 to a new location. Before the usermoves vehicle 10, another set of safety conditions may be confirmed,such as determining whether jacks 24 have retracted into vehicle 10and/or determining that camera 52 has retracted into module 18.

Modifications, additions, or omissions may be made to vehicle 10 withoutdeparting from the scope of the invention. For example, vehicle 10 maynot include jacks 24, but may include other devices to ensure vehicle 10is stable and in a safe level range to operate. Vehicle 10 may include atorsion bar, an anti-sway device, or other suitable mechanical device tolock out the suspension system of vehicle 10. In an embodiment, thetorsion bar mounts to the frame of vehicle 10 to stabilize vehicle 10.Module 18 may extend once vehicle 10 is stable and positioned in a safelevel range. As another example, once vehicle 10 stabilizes and levelswithin a safe range, module 18 may extend without locking the suspensionsystem of vehicle 10 because lifting mechanism 20 is within the wheelfootprint of vehicle 10. As yet another example, module 18 may extendfrom vehicle 10 once vehicle 10 is stable, but without leveling vehicle10 within a safe range. As another example, first portion 12 may includea monitor that displays images outside vehicle 10. A user may deploy anunmanned module 18 and view the images captured by a camera anddisplayed on the monitor. This allows a user to inspect the surroundingarea before getting in module 18 and deploying. As another example, roof32 of module 18 may include a device to detect any object above module18 that may obstruct its the deployment. This may be a sonar device.Detecting a possible obstruction may be configured as a safety conditionto satisfy before module 18 is allowed to deploy. Any suitable logic mayperform the functions of vehicle 10 and the components within vehicle10.

FIG. 2 illustrates module 18 in more detail. Module 18 includes anysuitable component that facilitates improved deployment capabilities andsurveillance activities. In the illustrated embodiment, module 18includes entrance 50, cameras 52 and 54, display 56, weather monitor 58,a user interface 60, one or more windows 62, and a climate control unit64.

Entrance 50 represents an entry into module 18 from first portion 12. Auser enters module 18 from first portion 12 through entrance 50 withoutexiting vehicle 10. Entrance 50 may be a hinged door, a sliding door, ora folding door. Entrance 50 may be made of a material that is resistantto the exterior elements when module 18 is deployed outside of vehicle10. Entrance 50 may also include a manual safety restraint, a cable, ora chain to prevent entrance 50 from opening once it is closed. In anembodiment, entrance 50 includes a sensor to indicate when entrance 50is closed. The closure of entrance 50 may be a safety condition checkedbefore module 18 deploys.

Cameras 52 and 54 represent any devices that detect images and/or soundsoutside module 18 for presentation to a user inside module 18. Forexample, cameras 52 and 54 may include an infrared detector, a motiondetector, a charge coupled device image sensor, a thermal imagingdevice, a closed circuit device, any other suitable camera, or anysuitable combination of the preceding. In the illustrated embodiment,camera 52 mounts inside roof 32 on an extendable and rotatable mast 53and is covered by cover 34. Camera 52 may automatically or manuallyextend from roof 32 to provide the user with a view of the surroundingarea. User interface 60 may include various controls, such as pan andzoom, that allow a user to control camera 52.

One or more cameras 54 mount on the bottom of module 18 and provideinformation, such as images and/or sounds, regarding the area undermodule 18 when module 18 is deployed. Because a user inside module 18cannot observe directly under vehicle 10, the visibility provided bycameras 54 offers an additional safety feature for the user. Cameras 54may mount on any suitable portion on the bottom of module 18. Forexample, cameras 54 may mount on opposite ends to provide a completeview of the surface below the deployed module 18. User interface 60 mayinclude various controls, such as pan and zoom, that allow a user tocontrol cameras 54.

Display 56 presents images received from cameras 52 and/or 54. Display56 may include a computer monitor, a liquid crystal display, a black andwhite display, and/or a color display. Display 56 may present the imagesin any suitable way, such as through a split screen or a sequentialimage cycle, either automatically or as directed by the user. Display 56may also present wind speed, temperature, barometric pressure, and/orany other indication from weather monitor 58. Display 56 may alsopresent operational information, such as sensor readings, an operationallog of module 18 including the timing of deployment and retractionsequences, and/or the positioning of vehicle 10.

Weather monitor 58 represents any device that monitors weatherconditions outside module 18; such as measuring wind speed, detectingrain, detecting lightning, determining the temperature, and determiningthe barometric pressure; and communicates the information to the user inmodule 18. Weather monitor 58 may include an anemometer, a laser windsensor, an ultrasonic wind sensor, any other device that monitorsweather conditions, or any suitable combination of the preceding. Module18 may deploy in most weather conditions. However, if the wind reaches ahigh speed, module 18 should not be deployed. A manufacturer and/or usermay pre-configure vehicle 10 with the maximum wind speed in which module18 may be deployed. If the wind speed reaches that predetermined maximumspeed, weather monitor 58 may activate an alarm that informs the user tolower module 18, or module 18 may automatically lower if weather monitor58 determines the wind speed reaches the predetermined maximum speed. Inan embodiment, module 18 may not be deployed in wind speeds greater thanforty miles per hour.

User interface 60 includes components that allow the user to operatemodule 18 and/or components within module 18. For example, userinterface 60 includes a toggle or button to extend lifting mechanism 20and deploy module 18, a toggle or button to deploy jacks 24, a joystickto control the positioning of cameras 52 and/or 54, and/or any suitablecombination of the preceding. Vehicle 10 may include any suitable numberof user interfaces 60. User interface 60 may mount to a particularportion of vehicle 10 or may mount to a remote device. In theillustrated embodiment, user interface 60 a mounts inside module 18,user interface 60 b mounts in first portion 12, and user interface 60 cis tethered. User interface 60 c may operate wirelessly to allow theuser to control vehicle 10, module 18, and their components from anysuitable location, including outside vehicle 10.

Window 62 represents a window that allows a user to view the surroundingarea from module 18. Window 62 may be tinted, tempered, or bullet proofand may slide open and close. Climate control unit 64 provides airconditioning and/or heating inside module 18. User interface 60 mayinclude a component to control climate control unit 64.

Modifications, additions, or omissions may be made to module 18 withoutdeparting from the scope of the invention. For example, a separatemonitor may display weather conditions and include an alarm to activatewhen unsafe weather conditions occur. Module 18 may also include a benchseat, an observation chair, folding tables, tactical lighting insideand/or outside module 18, or other additional equipment to facilitatesurveillance activities. For operation in an extreme environment, module18 may be completely bulletproof, comprising radio communications and/orweapons. Any suitable logic may perform the functions of the componentswithin module 18.

FIG. 3 illustrates an embodiment of components to operate vehicle 10 andmodule 18. Processor 100 and/or hydraulic unit 104 facilitate theoperation of lifting mechanism 20, jacks 24, actuators 110, userinterfaces 60, sensors 112 and 114, and proximity switches 116.

Processor 100 represents a device that is operable to manage theoperation of lifting mechanism 20, jacks 24, user interfaces 60,hydraulic unit 104, actuators 110, sensors 112 and 114, proximityswitches 116, and/or any other component in vehicle 10. For example,processor 100 receives a deploy signal to initiate deployment of jacks24. In response to the signal, processor 100 checks initial safetyconditions determined by sensors 112 before activating hydraulic unit104 to deploy jacks 24. Processor 100 also receives a surface signalfrom sensors 114 regarding the condition of surface 28. In response tothis signal, processor 100 activates hydraulic unit 104 to adjust jacks24 according to the condition of surface 28 and to meet another safetycondition by leveling vehicle 10. In the illustrated embodiment,processor 100 includes an internal level sensor 101 that determineswhether vehicle 10, module 18, and/or lifting mechanism 20 are level.Processor also may check additional safety conditions as determined bysensors 101 and proximity switch 116 before deploying module 18.Processor 100 activates hydraulic unit 104 to extend lifting mechanism20. Processor 100 includes any hardware and/or software that operates tocontrol the deployment and retraction sequences of module 18. Processor100 may be a programmable logic device, a microcontroller, amicroprocessor, any suitable processing device, or any suitablecombination of the preceding.

Memory 102 stores, either permanently or temporarily, data, operationalsoftware, or other information for processor 100. Memory 102 includesany one or a combination of volatile or nonvolatile local or remotedevices suitable for storing information. For example, memory 102 mayinclude random access memory (RAM), read only memory (ROM), magneticstorage devices, optical storage devices, any other information storagedevice, or a combination of these devices. While illustrated asincluding particular information, memory 102 may include any informationfor use in operation of vehicle 10. In the illustrated embodiment,memory 102 includes sensor data 106, code 107, and content data 108.

Sensor data 106 represents information received from sensors 112 and 114and information that processor 100 may use to process information fromsensors 112 and 114. For example, sensor data 106 includes a predefinedrange of degrees for vehicle 10 to be level. If vehicle 10 is not levelwithin this predefined range, module 18 may not deploy. In a particularembodiment, vehicle 10 must be level within two degrees fromfront-to-back and within two degrees from side-to-side before module 18deploys. As another example, sensor data 106 may include the level ofvehicle 10 as determined by sensor 112 a for comparison with the levelas determined by level sensor 101. In this embodiment, processor 100compares the levels determined by sensor 101 and sensor 112 a beforedeployment of module 18. The comparison should be within a suitablerange of degrees before deployment, such as within 0.5 degrees of oneanother. The additional comparison provides a redundancy within theleveling system to further improve the safety of vehicle 10. As anotherexample, sensor data 106 may include a predetermined time for vehicle 10to be stationary before processor 100 automatically initiates adeployment sequence. In this example, sensor 112 determines that vehicle10 is stationary for an amount of time and communicates this informationto processor 100. Processor 100 compares the received information to thepredetermined time stored in memory 102 and determines whether to beginthe deployment sequence. The predetermined time may be any suitableamount of time as configured by a user or a manufacturer of vehicle 10.Sensor data 106 may also include a maximum wind speed in which module 18may deploy. Processor 100 receives the actual wind speed from weathermonitor 58, compares the actual speed to the maximum wind speed, andinitiates an alarm that informs a user to lower module 18 and/orautomatically initiates a retraction sequence if the actual speed isgreater than or equal to the maximum speed. A manufacturer of vehicle 10or the user may pre-configure the maximum wind speed. Sensor data 106may also include information regarding the status of any of thefollowing: entrance 50, the ignition of vehicle 10, the gears of vehicle10, the voltage supply, the pressure in hydraulic unit 104, valves,hoses, and/or a reservoir in hydraulic unit 104.

Code 107 represents any suitable logic that controls the operation ofprocessor 100. Code 107 includes software, executable files, and/orother appropriate logic modules. For example, code 107 includesexecutable files capable of facilitating the processing of sensor data106.

Content data 108 represents any suitable information that processor 100receives from the user and/or cameras 52 and 54. Content data 108includes sounds, video, pictures, operational logs, times of deploymentsequences and retraction sequences, notes and observations from theuser, sensor readings, and/or weather conditions. Content data 108 maybe stored in memory 102 for later retrieval or transmitted wirelessly toa remote location for observation and further analysis.

Hydraulic unit 104 represents any suitable component that regulates theoperation of lifting mechanism 20, jacks 24, actuators 110, and/or anyother suitable component in vehicle 10. Hydraulic unit 104 facilitatesregulation of the flow of hydraulic fluid between valves and othercomponents. In an embodiment, hydraulic unit 104 includes a pump 101, ahydraulic control manifold 103 with a series of control valves, ahydraulic reservoir 105, and one or more supply and return hoses. Morespecifically, pump 101 pressurizes the hydraulic fluid for delivery tolifting mechanism 20 and jacks 24, and manifold 103 controls the flow ofpressurized hydraulic fluid from reservoir 105 through the controlvalves to selected components. This allows hydraulic unit 104 toseparately control lifting mechanism 20 and jacks 24 using a singlepump. As an example of operation, processor 100 receives a signal toinitiate deployment of lifting mechanism 20. Processor 20 turns on pump101 to control manifold 103. Manifold 103 distributes hydraulic fluid todeploy, adjust, and fixes jacks 24. Manifold 103 also deploys liftingmechanism 20 and extends module 18. Although FIG. 3 illustrates pump 101that delivers the pressurized hydraulic fluid to lifting mechanism 20and jacks 24, multiple pumps may be used to deliver the pressurizedhydraulic fluid. For example, a separate pump may deliver fluid tolifting mechanism 20 and jacks 24. As another example, vehicle 10 mayinclude multiple hydraulic units that may operate in a failover capacityif another hydraulic unit fails.

User interfaces 60 couple to processor 100 and communicate signals toprocessor 100 regarding deployment of module 18 and jacks 24, retractionof module 18 and jacks 24, and control of cameras 52 and 54. In theillustrated embodiment, user interface 60 a is mounted inside module 18,user interface 60 b is mounted in the interior of vehicle 10, and userinterface 60 c is mounted on a remote device that a user can use insideor outside of vehicle 10.

Actuators 110 represent a device operable to move or control a componentin vehicle 10. Vehicle 10 includes any number of actuators 110 tooperate the components. Actuators 110 may include hydraulic actuators,electrical actuators, electro-hydraulic actuators, electro-mechanicalactuators, mechanical actuators, solenoid actuators, or any othersuitable actuator. Actuators 110 may keep jacks 24 fixed, turn ontactical lighting, engage the parking brake, and/or control thedeployment and operation of cameras 52 and 54 through inputs from userinterface 60. Lifting mechanism 20 and jacks 24 are specific examples ofactuators in vehicle 10. In the illustrated embodiment, liftingmechanism 20 is a hydraulic actuator and jacks 24 are hydraulicactuators. In the illustrated embodiment, hydraulic unit 104 powerslifting mechanism 20 and jacks 24. Voltage from a battery source maypower other actuators 110.

Sensors 112 and 114 represent devices operable to determine a particularcondition and communicate a signal regarding the condition to processor100. Vehicle 10 may include any number of sensors 112 that provideinformation to processor 100 to determine whether safe conditions aresatisfied. For example, sensors 112 may include a speed sensor, aparking sensor, a current sensor, a weather condition sensor, a windspeed sensor, a position sensor, a level sensor, an occupancy sensor, acamera, a sensor to determine whether lifting mechanism 20 fullyretracts and/or fully extends, a battery charge sensor, a voltagesensor, a sensor to determine the hydraulic pressure in reservoir 105, asensor to detect overheating, a sensor to detect pressure in hosesand/or valves, a sensor to detect the exertion of pump 101, and/or anyother suitable type of sensor. A position sensor may include a globalpositioning system that provides location information of vehicle 10. Theuser of vehicle 10 may use this information to determine where toposition vehicle 10. Also, vehicle 10 may communicate its position to aremote location for tracking. In the illustrated embodiment, sensor 112a is a level sensor that determines whether vehicle 10, module 18,and/or lifting mechanism 20 are level. Processor 100 uses the signalcommunicated from sensor 112 a to determine whether a safety conditionis met before deploying module 18. Cameras 52 and 54 and weather monitor58 are specific examples of sensors. Additional sensors 112 maydetermine any other condition, such as whether jacks 24 fully retractbefore a user moves vehicle 10 or whether entrance 50 is closed.

In the illustrated embodiment, each jack 24 has a sensor 114 and aproximity switch 116. Sensor 114 facilitates determination of thecondition of surface 28. For example, sensor 114 is a pressure sensorthat determines the pressure caused by surface 28. The condition ofsurface 28 may cause jack 24 to exert varying amounts of pressure onsensor 114. Based on the information from sensor 114, processor 100 maydetermine to adjust jacks 24. In an embodiment, processor 100 retrievessensor data 106 to determine the maximum adjustability of jacks 24.Based on sensor data 106 and the signal from sensor 114, processor 100activates hydraulic unit 104 to adjust jacks 24 and level vehicle 10. Ifjacks 24 cannot adjust, processor 100 communicates a signal informingthe user that vehicle 10 is not level and lifting mechanism 20 will notextend. A user may determine to move vehicle 10 to a new location toextend module 18.

Proximity switch 116 communicates information regarding the position ofjack 24. For example, proximity switch 116 communicates a signal toprocessor 100 if jack 24 is retracted within vehicle 10 and communicatesanother signal to processor 100 if jack 24 is extended outside ofvehicle 10. Processor 100 may use the information from proximity switch116 to determine whether particular safety conditions are satisfiedbefore proceeding with the operation of vehicle 10. For example, beforemodule 18 deploys, processor 100 determines whether jacks 24 areextended and in place based on the signal from proximity switch 116. Asanother example, before a user moves vehicle 10, proximity switches 116communicate signals to processor 100 regarding whether jacks 24 areretracted into vehicle 10. Proximity switch 116 may include a mechanicalswitch or a magnetic switch.

In an exemplary embodiment of operation, processor 100 receives a signalto begin a deployment sequence. Processor 100 may receive the signalfrom user interface 60, receive a signal from sensor 112 that vehicle 10is in park for a predetermined amount of time, or any other suitablesignal. Before proceeding with the deployment sequence, processor 100checks initial safety conditions to confirm it is safe to deploy module18. For example, sensors 112 communicate signals informing processor 100that vehicle 10 is stationary for a predetermined period of time, thatvehicle 10 is in park, that the vehicle ignition is off, that theemergency parking brake is engaged, and/or that entrance 50 to module 18is closed.

Upon checking these initial safety conditions, processor 100 activateshydraulic unit 104. Manifold 103 in hydraulic unit 104 distributeshydraulic fluid through control valves to jacks 24, and jacks 24 beginto extend from base 22. Once jacks 24 have completely extended, sensor114 determines the condition of surface 28 and sensor 112 a determineswhether vehicle 10 is level. Level sensor 112 a communicates a signalinforming processor 100 whether vehicle 10 is level within a predefinedrange. Processor 100 may also compare the signal provided by levelsensor 112 a to the level determined by the internal level sensor 101.If vehicle 10 is not level, processor 100 may communicate another signalto activate hydraulic unit 104 and cause manifold 103 to adjust jacks24. Sensor 112 a again determines whether vehicle 10 is level. Ifvehicle 10 is level, deployment of module 18 may begin. If vehicle 10does not become level within the predefined range, module 18 will notextend.

Modifications, additions, or omissions may be made to the controlcomponents. Vehicle 10 may include a hydraulic system having apolyethylene tank, an electric motor, and integrated multi-battery powersupply. Vehicle 10 may include a manual dump valve that overrides thecontrol valve and allows lifting mechanism 20 to return to the stowedposition in the case of an electrical or hydraulic failure. Vehicle 10may also include an orifice to control the speed of descent of module18. In a particular embodiment, lifting mechanism 20 includes the valveand the orifice. As another example, vehicle 10 includes anelectrically-operated hydraulic solenoid valve that prevents liftingmechanism 20 from lowering in the event of a hose failure. The levelingsystem of vehicle 10 may also aide in the maintenance of vehicle 10,such as changing a flat tire or fixing components on the second side ofbase 22. In an embodiment, a user may control the operation of jacks 24independent of processor 100. Using user interface 60, a user may levelvehicle 10 independent of processor 100. Once the user levels vehicle10, processor 100 may enable lifting mechanism 20 to extend. As yetanother example, a user may operate cameras 52 and 54 independently ofprocessor 100.

FIGS. 4A-4D illustrate vehicle 10 through the phases of operation. Morespecifically, FIGS. 4A-4D illustrate vehicle 10 before deployment ofmodule 18, during deployment, and after deployment.

FIG. 4A illustrates an embodiment of vehicle 10 that deploys module 18.Vehicle 10 houses module 18 and lifting mechanism 20. Module 18 couplesto lifting mechanism 20. When module 18 is within vehicle 10, roof 32 ofmodule 18 couples to top 30 of third portion 16, which creates a tightseal. Cover 34 couples to roof 32 to enclose camera 52.

A user may position vehicle 10 in any suitable location. Module 18 andlifting mechanism 20 remain fixed in the retracted position while a userpositions vehicle 10.

FIG. 4B illustrates an embodiment of vehicle 10 after deployment ofjacks 24. When a user positions vehicle 10 in the appropriate locationand processor 100 checks the safety conditions, jacks 24 extend fromvehicle 10 to keep vehicle 10 stationary, stable, and level when module18 deploys. A manufacturer or user of vehicle 10 may configure anysuitable safety conditions to be satisfied before jacks 24 extend fromvehicle 10. These initial safety conditions may include vehicle 10 beingin park, vehicle 10 being stationary for a predetermined period of time,the ignition of vehicle 10 being off, the emergency parking brake beingengaged, an entrance to module 18 being closed and/or a user being inmodule 18.

Jacks 24 have three different modes of operation. In a first mode, jacks24 extend from vehicle 10. In the second mode, jacks 24 adjust to levelvehicle 10. In an embodiment, jacks 24 adjust in response to theconditions of surface 28. In the third mode, jacks 24 become fixed. Oncejacks 24 are stable and fixed, module 18 may deploy.

Once jacks 24 deploy, additional safety conditions may be satisfiedbefore the deployment sequence continues. These safety conditions mayinclude confirming that vehicle 10 is level, confirming that jacks 24are extended and stable, and/or confirming that an obstruction is notabove vehicle 10 before module 18 extends.

FIG. 4C illustrates an embodiment of vehicle 10 during deployment ofmodule 18. After vehicle 10 is level and jacks 24 are fixed in position,lifting mechanism 20 actuates and begins to extend. Module 18 extendsout of opening 36 of third portion 16 as lifting mechanism 20 raises. Asmodule 18 moves, the seal between top 30 and roof 32 decouples.

FIG. 4D illustrates an embodiment of vehicle 10 with module 18completely extended. When lifting mechanism 20 completely extends,module 18 is fully deployed outside of vehicle 10. In the fully deployedmodule 18, a user may have an observation height of over twenty-fivefeet from surface 28.

In the illustrated embodiment, cameras 52 and 54 are in use. Camera 52extends out of roof 32, and cameras 54 under module 18 are used.

FIG. 5A is a flowchart that illustrates a deployment sequence of module18. At step 500, a user positions vehicle 10. At step 502, thedeployment sequence is activated. For example, a user may activate thedeployment sequence by entering module 18 from first portion 12 andpressing a button. This sends a deploy signal to processor 100. Asanother example, sensor 112 may determine that vehicle 10 is in park fora predetermined amount of time, and sensor 112 communicates a deploysignal to processor 100. Processor 100 may then automatically activatethe deployment sequence.

Processor 100 performs an initial check of the safety conditions at step504. The safety conditions checked may include determining whether agear shift of vehicle 10 is in park, determining whether the ignition ofvehicle 10 is off, determining whether the emergency parking brake isengaged, determining whether entrance 50 to module 18 is closed, and/ordetermining whether a user occupies module 18. In an embodiment, amanufacturer of vehicle 10 or the user pre-configures the safetyconditions for processor 100 to check. At step 506, processor 100determines whether the safety conditions have cleared. If all of thesafety conditions have not cleared, processor 100 determines at step 508whether the status of a safety condition has changed. For example,turning off the ignition of vehicle 10 may be a safety condition. If theignition is not off when processor 100 initially checks the safetyconditions, processor 100 may determine that the status of a conditionchanges when the user turns off the ignition of vehicle 10. Processorthen checks the safety conditions again from step 504. At step 506,processor 100 again determines whether all the safety conditions havecleared.

When the initial safety conditions clear, processor 100 activateshydraulic unit 104 to extend jacks 24 at step 510. To extend jacks 24,manifold 103 distributes hydraulic fluid through control valves to eachjack 24. Jacks 24 operate in a first mode when extending from vehicle10. At step 512, sensor 114 determines the condition of surface 28 andcommunicates a signal to processor 100. Processor 100 determines atstep. 514 if the condition of surface 28 is safe. For example, ifsurface 28 severely angles, vehicle 10 cannot become level and thesurface condition is not safe. If the surface condition is not safe,jacks 24 retract into vehicle 10, and a user returns to first portion 12and moves vehicle 10 to a new location.

At step 516, sensor 112 a determines whether vehicle 10 is level. Ifvehicle 10 is not level, processor 100 determines whether jacks 24 havereached a maximum adjustment limit at step 518. If processor 100 cannotadjust jacks 24 further, jacks 24 retract into vehicle 10, a userreturns to first portion 12 and moves vehicle 10 to a new location. Ifprocessor 100 can adjust jacks 24, jacks 24 operate in the second modeand adjust at step 520. Processor 100 again determines at step 516whether adjusting jacks 24 has leveled vehicle 10. If vehicle 10 is notlevel, processor 100 may continue to adjust jacks 24 or jacks 24 mayretract into vehicle 10 for a user to relocate vehicle 10.

If vehicle 10 is level, jacks 24 become fixed in a third mode at step522. At step 524, processor 100 may reconfirm the initial safetyconditions before deploying module 18. Processor 100 may also confirmadditional safety conditions, such as confirming that jacks 24 areextended and stable and/or confirming that an obstruction is not abovevehicle 10 before module 18 extends. At step 526, module 18 begins tomove from a retracted position to an extended position. In anembodiment, a user activates the extension of module 18 by depressingand holding a button. Processor 100 activates hydraulic unit 104, whichcauses manifold 103 to distribute hydraulic fluid to lifting mechanism20, and lifting mechanism 20 extends. If module 18 is not fully extendedat step 528, module 18 continues to extend. Once module 18 fullyextends, processor 100 module 18 fixes in place at step 530.Surveillance cameras 52 and 54 are activated and used at step 532. Auser may then complete surveillance activities in the extended module18. Once the user concludes the surveillance activities, the user mayinitiate a retraction sequence to return module 18 to vehicle 10.

Modifications, additions, or omissions may be made to the flowchart. Forexample, processor 100 may not reconfirm the initial safety conditionsat step 524. As another example, lifting mechanism 20 may not extendfully and a user may stop lifting mechanism 20 at any position duringthe extension of module 18. Additionally, the steps may be performed inany suitable order, and any suitable component in vehicle 10 may performthe steps.

FIG. 5B is a flowchart that illustrates a retraction sequence of module18. At step 550, processor 100 determines whether to activate theretraction sequence. In an embodiment, a user may press a button thatcommunicates a signal to processor 100 to initiate the retractionsequence. In another embodiment, processor 100 may determine that thewind speed reaches a maximum wind speed and automatically initiates aretraction sequence.

At step 552, cameras 52 and 54 deactivate and are stored. At step 554,module 18 begins to lower into vehicle 10. In an embodiment, a userdepresses and holds a button to lower module 18. Processor 100determines at step 556 if module 18 is in the stowed position. If module18 has not completely retracted, lifting mechanism 20 continues toretract and lower module 18.

When in the stowed position, roof 32 of module 18 couples to top 30 ofthird portion 16 to form the seal. Once module 18 and lifting mechanism20 retract to the stowed position, jacks 24 retract from surface 28 intovehicle 10 at step 558. Jacks 24 operate in the first mode whenretracting into vehicle 10. The user may now move vehicle 10 to a newlocation at step 560.

Modifications, additions, or omissions may be made to the flowchart. Forexample, a user may stop lifting mechanism 20 at any position during theretraction of module 18. As another example, a manufacturer or user ofvehicle 10 may configure vehicle 10 to check certain safety conditionsbefore a user can move vehicle 10 from the surveillance position. Thesesafety conditions may include determining whether jacks 24 haveretracted into vehicle 10 and/or determining that camera 52 hasretracted into module 18. Additionally, the steps may be performed inany suitable order, and any suitable component in vehicle 10 may performthe steps.
